Limited literature surrounds the use of high dose, rapid vaccination regimens in cirrhotic patients. The aims of this study were therefore Trichostatin A mw to 1) assess the effectiveness of high dose, rapid vs. standard dose HAV and HBV regimens in a mixed aetiology and disease severity cirrhotic population and 2) determine clinical associations with response to vaccination. Methods: Prospective, non-randomized controlled trial. Standard HAV schedule was; intramuscular Havrix® 720 μg at 0, 1 and 6 months with a 1440 μg booster if non-immune after 3 doses. High dose HAV schedule was; 1440 μg at 0, 1 and 2 months with the schedule repeated as a booster if non-immune after 3 doses. Standard HBV schedule

was; intramuscular Engerix®-B 20 μg at 0, 1 and 6 months with a 40 μg booster if non-immune after 3 doses. High dose HBV schedule was; 40 μg at 0, 1 and 2 months (120 mcg) with the schedule repeated as a booster

(120 mcg) if non-immune after 3 doses. Differences Metformin manufacturer in response rates between standard and high dose regimens were compared using Fishers exact or chi-square test. The following variables (age, gender, aetiology, MELD score, Child Pugh score, INR, albumin, creatinine, bilirubin, smoking status, drinking status, presence of renal dysfunction) were tested for association with response using stepwise logistic regression. Results: For HAV schedules 62 and 37 patients

received standard and high dose regimens, respectively. The overall clinical characteristics selleckchem of this population were; mean age 56 years, male 63%, alcohol liver disease 46%, mean MELD score 10.2, with similar clinical characteristics for standard and high dose groups. The response rates were 87.1% and 97.3% for standard and high dose regimens, respectively (p = 0.15). The only factor that was independently associated with response was age (OR 0.94, 95%C1 0.88–1.0, p = 0.005). For HBV schedules 81 and 48 patients received standard and high dose regimens, respectively. The overall clinical characteristics of this population were; mean age 58 years, 65% male, 56% hepatitis C, mean MELD score 11.1 with similar clinical characteristics for standard and high dose groups. The response rates were 60.5% and 70.8% for standard and high dose regimens, respectively (p = 0.24). Factors independently associated with response included; female gender (OR 3.1, 95%C1 1.04–9.15, p = 0.042) and non-alcoholic fatty liver disease vs. hepatitis C as aetiology (OR 0.13, 95%C1 0.03–0.56, p = 0.006). The mean increase in per patient cost was $50 and $44 for high dose hepatitis A and B vaccination, respectively. Conclusions: In cirrhotic patients an approximately 10% improvement in HAV and HBV responses can be obtained using high dose, rapid vaccination regimens, relative to standard regimens.
